From: Rigid soles improve balance in beam walking, but improvements do not persist with bare feet
Representative stick figures of example subject S4 walking along the beam shown in the frontal plane. The color of the skeletons becomes lighter as the subject progresses forward along the beam axis (i.e., y-axis). (a) When the lower-body segments rotated clockwise about the beam, the upper-body segments rotated counterclockwise about the hip. (b) When the lower-body segments rotated counterclockwise about the beam, the upper segments rotated clockwise about the hip.
